Improvement in sugar-pans

A. T. XVILDER, OF LA FORTE, INDIANA.

IMPROVEMENT IN SUGAR-FANS.

Specification forming part of Letters Patent No. 38,995, dated June 23, 1863.

To all whom it may concern:

Be it known that I, A. T. WILDER, of La Porte, in the county of La Porte and State of Indiana, have invented a new and Improved Sugar-Pan; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a longitudinal vertical section of my invention. Fig. 2 is a transverse vertical section of the same. Fig. 8 is a plan of the furnace, the pan having been removed to show the interior of said furnace.

Similar letters of reference in the three views indicate corresponding parts.

To enable others skilled in the art to make and use my invention, I will proceed to de scribe it.

A represents a sugar-pan, the bottom a of which is cast of iron in three parts, I) c (I, one part to fit under the compartments B O D of the pan. The parts I) c are provided with offsets or lips e to make tight joints between their ends and the adjoining parts of the bottom, and said bottom may be made with ribs or flanges to fit the sides of the pan and to retain the same in place. The sides of the pan are made of wood, and they are firmly secured to the bottom. Transverse partitions separate the several compartments, and faucets g, inserted into these partitions, form the means of communication between the compartments. These faucets are operated by handles h, and they are preferable to ordinary gates, because they are less liable to stick and they can be easily set to regulate the current from one compartment to the other. The pan A is placed on the furnace E, built up of brick or other suitable material. The upper edge of this furnace corresponds to the bottom of the pan, and it is so arranged that an air-channel, t, is formed under the front edge of the first compartment. Said brick-work is also provided with a recess, on its side under the second and third compartments, so as to expose a portion of each of these compartments to a current of cold air. By these means the scum is caused to accumulate on one side or end of If the dampers are turned down, as shown in Fig. 2 of the drawings, all the heat from the fire comes in contact with the-bottom of the pan; but if it is desired to reduce the heat under the two last compartments, 0 D, the damper G is turned up to the position shown in dotted lines in Fig. 1, causing the hot air and products of combustion to turn down under the damper F, so that the bottoms of the compartments 0 D do not come in direct c011- tact with the heat from the furnace. By turning the damper G down and the damper F up, the last compartment, D, can be cooled off, while the boilingin the compartments B O .proceeds without interruption.

It is obvious that by turning the dampers up or down more or less the heat under each compartment of the pan can be regulated at pleasure, and by the ratchet-wheels and pawls the dampers are retained in any position in which they may be brought, and their posi tion can be nicely adjusted.

What I claim as new, and desire to secure by Letters Patent, is

The construction of the sections of the pan with lips e thereupon, combined and operating together in the manner and for the purpose herein shown and described.

A, T. VILDER.
